Since last August, I have put about 1500 rounds through my 338 MRAD Lapua Magnum. I only clean after 200-300 rounds or when my accuracy starts to drop. Cleaning is a breeze ( I think due to break in mentioned in this article), using only 5-7 patches with BoreTech Eliminator cleaning both carbon and copper and patches are clean. No brushes-even nylon. Then I run 1 patch with a few drops of Kranoil and I'm done. Barrel still looks like new, but I don't have a bore scope. I do lube the bolt after every 2 sessions. Still shooting 1/2 MOA all day out to 1000 yds.
